A Novel Method for Image Enhancement
In this paper a novel method for image enhancement using PDTDFB (Pyramidal Dual-Tree Directional Filter Bank) and interpolation has been adopted. Generally, in digital images since the different kinds of noise highly affects various image processing techniques it is always better to perform denoising first. Here, first of all the image is decomposed into two different layers namely low pass sub band and high pass sub band after which denoising is being performed on both the layers so as to smoothen the image. The smoothened image is then interpolated using edgepreserving interpolation and then amplified. Finally, the HR (High Resolution) image is being obtained by performing image composition.
